Subject [jira] [Created] (HBASE-8550) 0.94 ChaosMonkey grep for master is too broad
Date Tue, 14 May 2013 21:25:16 GMT
Sergey Shelukhin created HBASE-8550:
---------------------------------------

             Summary: 0.94 ChaosMonkey grep for master is too broad
                 Key: HBASE-8550
                 URL: https://issues.apache.org/jira/browse/HBASE-8550
             Project: HBase
          Issue Type: Bug
          Components: test
    Affects Versions: 0.94.8
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin
            Priority: Minor
             Fix For: 0.94.8


As a true anarchist, ChaosMonkey in 0.94 knows no masters, so it tries to kill all of them
("grep master"). If HBase user doesn't have enough permissions, some of the kills fail (in
one case, Postfix master), and the entire command throws an exception; thus HBASE-7844 happens
and the entire restart-master action fails, with master already killed, and not restarted.

In trunk, "proc_" was added to process and the grep filter, but in 94 it was deemed to break
compat. We need to add something like "grep hbase" there.
